Why is this simple rewriterule failing to function?

I have two rules to redirect to relevant front controllers:

RewriteRule ^api/?.*$ api.php [NC,L]
RewriteRule ^.*$ web.php [NC,L]

Is there a reason why local开发者_如何学JAVAhost/api/a fails to be caught by the first rule?

Try this:

If its in the root,

RewriteBase /
RewriteRule ^api/?.*$ api.php [NC,L]
RewriteRule ^.*$ web.php [NC,L]
